Got an 83 Ram Charger with a 440 today!

Clean and straight was a definite plus! But 2 wheel-drive is what I was wanting. Looking for something of a street-rod / pro-street look eventually. Something like the white Ram Charger but I want the tire sizes that are on this orange chevy, (rears are 29X12.50-15 and fronts are 245X60-15).
